Do I have to Dispose the SQLiteCommand objects?

Question

How do I treat the SQLiteCommand object, do I have to call Dispose() after ExecuteScalar, ExecuteNonQuery

Answer 1

It's best-practise to dispose everything that implements IDisposable as soon as you're finished with it because it might use unmanaged resources.

This should be done with the using-statement since it wraps the code that uses this object and because it disposes it also in case of an exception.

using(var con = new SQLiteConnection(conString))
using(var cmd = new SQLiteCommand(con))
{
    con.Open();
    // ...
} // also closes the connection
